On their own, Chris Brown and Trey Songz each know how to make women melt. When the R&B heavyweights join forces forces on one cut, there's no telling what will happen; maybe ladies will turn into steam à la the Wicked Witch of the West? After a listen to Breezy's new single, Songs on 12 Play, that doesn't seem impossible. Mel & Mus handle production on this languid bedroom burner, serving a leisurely synth backdrop as the collaborators deliver steamy verses inspired by R. Kelly's debut set. For 12 Play and much more, cop Chris Brown's X LP when it drops via RCA Records next Tuesday, the 16th.
